"

Even though soloists were not popular around 1900 because of the campaign against “virtuosic music and in favor of pure, serious music”[citation needed], Long participated in the performance of Franck’s Variations Symphoniques, receiving a positive review from Fauré saying: “To reach Perfection, the interpretation of the piano part of the Variations Symphoniques demands the clean, solid, impeccable virtuosity, the musical quality and proper sentiment, that the truly remarkable artist Marguerite Long exhibited yesterday. One could not play with better fingers, with more clarity and good taste, with a more charming and natural simplicity, and, I should add, with greater success." (November 23, 1903)
